N220 Provides excellent abrasion resistance, high tensile, good tear properties, moderate electrical conductivity. Used in truck and passenger tires, and mechanical goods.
N234 Provides superior abrasion resistance vs. N220. Excellent wear and extrusion properties typical of improved process high structure blacks. Used in all elastomers, especially SBR/BR blends for treads and tread rubber.
N326 Low structure, high reinforcement, high tensile strength, very resistant to tear and chipping in natural rubber compounds. Used in mechanical goods, tire carcasses, belts and off the road tread.
N330 Provides good abrasion resistance with high resilience, easy processing, good tensile and tear properties. Wide range of applications in natural rubber and synthetic rubber compounds for both tires and mechanical goods.
N339 Provides superior wear and cut growth resistance vs. N347. Excellent wear and extrusion properties typical of improved process high structure blacks. Used in passenger treads, tread rubber and mechanical goods.
